peak symmetry

Question

How does MassHunter Qual calculate peak symmetry? You just do integration and receive data where symmetry value is calculated e.g. 1.4 . The you do system suitabiity (in Qual for e.g. European Pharmacopeia) and your symmetry is 0.67 ?? Why is that? 
 Can I get system suitability for Quant? There are some columns in Quant like Symmetry, SNR, FWHM, but I can't calculate Resolution etc. 
 Thank you

Hello RGK , 
 From what I can find, both Qual and Quant use the following formulas/definitions for symmetry depending on whether or not a particular pharmacopeia is selected. This is from the Quant Dataset manual.

Default would be used if no pharmacopeia is selected, which would be the case in Qual if system suitability is not enabled. 
 Regarding the columns in Quant, while some values are always calculated, others are only calculated if an outlier/limit is specified. The resolution is one such calculation, where the calculation type and limit must be specified for the Peak Resolution outlier before a value is calculated.
